The 2010 Geneva Motor Show edition saw the presentation of two green Italian Beauties. But the similarities between the two models stop there. In fact, while the Ferrari 599GTB HY-KERS is a Hybrid concept using a technology similar to the KERS system used in the 2009 F1 season by Ferrari and some other teams, the Lambo is a more extreme (non hybrid) version and the most powerful yet of the Gallardo.

The two cars go in two different directions. The Lambo philosophy is simple: more power and less weight. But on the Ferrari side things get a bit more complicated with extra electric power and... more weight.

The 100Hp electric motor used in the 599 HY-KERS is attached to the rear of the 7 speed F1 gear box and gets electricity from a Lithium ion battery mounted on the chassis in a way that helps the car keep the same weight distribution over the standard 599GTB which means similar handling as well. The extra electric power generated from braking will help the car deal with the extra weight and lower its fuel consumption while CO2 emissions are said to be improved by 35%. A production version is planned to come sometimes near 2015 which leaves to Ferrari the time to improve its hybrid technologies and focus on weight saving.

When talking about the Gallardo things become more easy: lighter and more powerful. With a weight of 1340 Kg and a 570 Hp high rev Lamborghini V10, the new Superleggera is capable of doing the 0 to 100 km/H (0-62mph) sprint in 3.4 seconds and can reach a top speed of 324 Km/h (202 mph).

Some of the most noticeable changes are the Reventon styled front air intakes, the rear spoiler and a huge rear diffuser. Weight saving has been achieved by the extensive use of carbon fiber. Howevver, the car keeps air conditioning and electric windows.

Which one would you chose? For me, the ranging bull is the obvious choice, at least for the moment.
